st: Importing data with infile: Identifying records with problems

Is there any way that Infile can report a specific part of a record when
there is an error as opposed to a record number? I am importing dozens
of scanned files and getting hundreds of lines like the following:

'*' cannot be read as a number for tfake[153]
'*' cannot be read as a number for corl[157]

It would be much easier for me to deal with these if instead of the
record number, e.g., 153, I could somehow instruct stata to report the
first six characters of the record with the problem since those
characters represent the research participant's serial number. Also, the
record numbers start at one for every text file that is imported and it
therefore becomes quite a headache to manage both a relative record
number and file identifier.

Thanks for any advice.
